Benefits of the Hadith: (… from Abu Hurayrah (may Allah be pleased with him) who said: The Prophet (peace and blessings be upon him) said: “The Jews and the Christians do not dye [their hair], so differ from them”)

The Shaykh : Yes, his statement: The apparent meaning is that they do not dye the white of gray hair, and it is not an absolute negation.
That is: dye [your hair]. This command is for recommendation, and its apparent meaning is that it is obligatory, because the default ruling regarding differing from the Jews is obligation. However, considering that some of the Companions (may Allah be pleased with them), among their elders, did not dye their hair, and this became well-known among them without being censured, it indicates that they understood the command to be for recommendation, not obligation.
And his statement here implies the permissibility of differing from them in every color, but there is what has been reported indicating that it is not permissible to dye with black. As for other colors, there is nothing wrong with them. This is because dyeing with black contains something of a type of opposition to the wisdom of Allah (Mighty and Majestic), for the color of youth is black. So if you turn this white into black, it is as if you are opposing Allah (Mighty and Majestic), and it is as if there is a kind of objection to Allah (Glorified and Exalted is He). Therefore, dyeing with black is forbidden according to the stronger position, even though some scholars said it is disliked. But the correct view is that it is forbidden, and that it is not permissible for a person to dye with black. However, there is a dye that is between black and red, meaning it is dark, such that katam is mixed with henna and dyed with it. This makes the hair between black and red, so it does not fall under the prohibition.
The apparent meaning of the hadith is that this is general for the head and the beard, and it is so, especially since the reason for the hadith is that Abu Quhafah was brought to the Prophet (peace and blessings be upon him) and his head was as white as a thaghamah, so he said: Yes.
